	// HACK: This applies the workaround suggested in

Functions

func MakeK8sService

func MakeK8sService(route *v1alpha1.Route) *corev1.Service

MakeK8sService creates a Service that targets nothing, owned by the provided v1alpha1.Route. The purpose of this service is to provide a domain name for Istio routing.

func MakeVirtualService

func MakeVirtualService(u *v1alpha1.Route, tc *traffic.TrafficConfig) *v1alpha3.VirtualService

MakeVirtualService creates an Istio VirtualService to set up routing rules. Such VirtualService specifies which Gateways and Hosts that it applies to, as well as the routing rules.
